Abstract

Read online

Polar growth of pollen tubes is established by polar localization of ROP1 GTPase activity at the apical tip. Here, Li et al. identify REN4 as a ROP1 interaction partner that restrains the ROP1 distribution to the apex by promoting ROP1 endocytosis from lateral domains of the pollen tube membrane.
